Gnomes live underground, and the natural darkness and rugged terrain of their surroundings provide ideal conditions for enemies to hide. In an effort to catch prowling and skulking creatures of all types, gnomes developed the alarm-o-bot. The small robot looks like a child’s toy with various wires and sensor arrays jutting out in all directions, and a police-siren light for a head, enabling it to “see” in the dark. When it detects a living creature or any sort of movement, it emits a high-pitched warning, “Intruder Alert!”. The leper gnomes in Gnomeregan make heavy use of this device

In addition to the Gnomeregan Alarm-O-Bot, players with the Engineering skill (Gnomish Engineering) can create one of their own that sends out a pulse every 7 seconds which detects stealthed enemies
